Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating containers using heat-shrinkable films or shape-memory resins face limitations in deformation mechanisms, particularly in projecting outwardly to form insulating holders without manual intervention and maintaining a low stack height for efficient storage and handling.
Innovation Solution
A shrink-deformable film is bonded to the exterior sleeve of a container, allowing it to deform into an insulating holder when heated or subjected to microwaves, eliminating the need for manual deformation and enabling a low stack height configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an exterior sleeve is manually pulled-up and pulled-down to deform slit forming sections into an insulating holder, then the container provides heat insulation, but it requires manual intervention and increases handling complexity
Solution Approach 1:
The exterior sleeve automatically deforms the slit forming sections into an insulating holder through self-service mechanisms. The sleeve is configured to project outwardly and compress the slit forming sections without requiring manual intervention, allowing the container to provide heat insulation autonomously.
Solution Approach 2:
The manual mechanical action of pulling-up and pulling-down the exterior sleeve is replaced by an automatic deformation mechanism. The slit forming sections are designed to deform automatically through their structural configuration, substituting the need for manual mechanical operation.
2Reliability
If the exterior sleeve is deformed into an insulating holder by manual intervention, then heat insulation is achieved, but the stack height increases and storage efficiency decreases
Solution Approach 1:
The exterior sleeve transitions from a flat state during storage to a deformed insulating holder state during use. This dynamic transformation allows the container to maintain a low stack height when not in use while providing heat insulation when needed, optimizing both storage efficiency and functional performance.
Solution Approach 2:
The slit forming sections are nested within the exterior sleeve in a compact configuration during storage. When deformed, they expand outward to form the insulating holder, similar to a nested doll structure that can be compressed for storage and expanded for use, thereby maintaining low stack height while providing insulation.
3Extent of automation
If a heat-shrinkable film is used to deform the exterior sleeve, then automatic deformation is achieved, but the film must be directly heated which increases energy consumption
Solution Approach 1:
A shrink-deformable film made of shape-memory resin is used as an intermediary between the heat source and the exterior sleeve. This film can be indirectly heated by microwave radiation, reducing direct heat exposure and energy consumption while still achieving automatic deformation of the exterior sleeve into the insulating holder configuration.
4Productivity
If the container is designed with a low stack height configuration, then transport efficiency improves, but the exterior sleeve deformation mechanism becomes more complex
Solution Approach 1:
The exterior sleeve is designed with localized slit forming sections that deform into insulating holders only at specific locations where heat insulation is needed. This local quality approach allows the container to maintain a low stack height overall while providing insulation functionality, avoiding the need for complex deformation mechanisms throughout the entire structure.

AI summary
The present invention relates to an improvement of an insulating container wherein either one of an upper portion or a lower portion of an exterior sleeve is fixed to a container main body so as to be fit onto the container main body, and a slit forming section including a group of slits formed on the exterior sleeve is compressed in an up-and-down direction to have the slit forming section project outwardly from the exterior sleeve in order to form an insulating holder. An inside wall surface of the exterior sleeve is provided with a shrink-deformable film, an upper portion of the shrink-deformable film is bonded to an upper portion of the exterior sleeve beyond the slit forming section, whereas a middle section covering the slit forming section is free from bonding, a lower portion is bonded to a lower portion of the exterior sleeve beyond the slit forming section, and the shrink-deformable film is shrunk to have the slit forming section project outwardly from the exterior sleeve.
